NAME

pwgrd - password and group hashing and caching daemon

SYNOPSIS

/usr/sbin/pwgrd

[-d][-l logﬁle]

DESCRIPTION

pwgrd provides accelerated lookup of password and group information for libc routines like

getpwuid

and getgrname . pwgrd implements per request type caches and hashtables as appropriate. When the

corresponding routine in libc is called, a request is issued to

pwgrd

via a Unix domain socket connection.

pwgrd determines whether it can satisfy the request, returning the appropriate results to the requesting

process.

Options

pwgrd recognizes the following options and command-line arguments:

-d Debug mode. Do not become a daemon. Issue additional diagnostic messages. Instead of log-

ging message via syslog, issue messages to stderr.

-l logfile Logﬁle. In addition to logging via syslog, pwgrd will write log messages to logﬁle.

pwgrd modiﬁes its behavior depending on whether or not the local machine is using some form of NIS for

password or group information. When NIS is being used, the hashtables corresponding to that service are

not generated or consulted. Therefore only caching is provided for those requests.

AUTHOR

pwgrd was developed by the Hewlett-Packard Company.
